When assembling the pump, the water pipe, and the drive shaft, the connecting parts should be gradually tightened into the well to prevent the parts and tools from falling into the well. The cable of the submersible pump should be bundled on the water pipe;
1. When the threaded connecting water pipes are connected to each other, the oil should be added and should not be filled with hemp and lead oil; the end face of the pipe should be fitted with the bearing bracket (long shaft deep well pump) or directly attached, and the two pipes are screwed into the joint. The depth of the pipe should be equal; the flanged water pipe should be gasketed between the flange end faces;
2. When the pump seat is connected with the water pipe and placed on the foundation, if the well pipe is slightly skewed, the pump seat should have a corresponding deflection (do not simply correct the level of the pump seat); the gap between the pump base and the foundation should be Wedge iron fills.
3. The long shaft deep well pump indication should meet the following requirements: When the drive shafts are connected to each other, the end faces of the two shafts shall be fitted together, and the depth of the two shafts screwed into the coupling joints shall be equal; The motor and the pump base should be closely fitted, and no padding should be added between them. For example, when the motor shaft and the motor hollow shaft are different shafts, the inclined horn should be adjusted between the pump base and the foundation.
4. The submersible deep well pump should meet the following requirements: a. After the pump and motor are assembled, the submersible motor should be filled with clean water through the motor irrigation; b. The depth of the submerged water should not exceed 70 meters, if it must exceed 70 When the meter is used, the motor stator windings, cables and joints should be tested for water pressure resistance.
